Title:

The catadioptric system which has a multiple reflection element for picturizing by a Taikai talkative

Document Type and Number:

Japanese Patent JP6255268

Kind Code:

B2

Abstract:

A catadioptric system includes a first catadioptric group, a second catadioptric group, and a lens group disposed in axial alignment with each other. The first catadioptric group includes a solid lens having an input surface, a primary reflective surface, secondary reflective surface and an exit surface. The primary reflective surface is a curved surface concave towards the secondary reflective surface. A light flux entering through the input surface undergoes more than two reflections between the primary and secondary reflective surfaces, prior to exiting through the exit surface. At least one of the primary reflective surface and secondary reflective surface has a continuous and smooth topological profile.
